Prosecutors said Thursday that they believe Watts committed the murder at the family’s residence. Thursday evening, the city officials said the authorities had found two bodies, “who (they) have strong reason to believe” are the Watts’ 3 – and 4-year-old daughter.

Watt is expected to be formally charged Monday on three counts of first-degree murder and three charges of tampering with physical evidence, but will not murder responsible for the death of the couple’s unborn child, Denver’s FOX 31 reported.

While Colorado does increase the penalties for crimes committed against pregnant women, not to grant “personhood” status of an unborn fetus.

Under Colorado law, a person can be charged with fetal murder only if it can be proven that the baby can survive outside the womb.

In 2015, a woman in Longmont, Colorado, was accused of stabbing of a pregnant woman in the abdomen and the removal of her baby. The woman was not charged with murder by Colorado’s laws relating to fetal personality, the Durango Herald reported.

Colorado lawmakers then tried and failed to change state laws with regard to fetal murder. A proposed measure, Senate Bill 268, would have made killing a fetus a murder, except in certain circumstances. The bill was largely supported by Republicans but opposed by Democrats on the grounds that it threatened abortion rights.

At the time, Planned Parenthood called the bill “dangerous for women,” and accused proponents of “disregard of the values and of Colorado voters.”

There are currently 38 states that have fetal homicide laws.
